The NORSOK M-710 RGD test is a standard for the performance of rubber sealing materials under rapid gas decompression (RGD) conditions. The test is designed to evaluate the ability of sealing materials to withstand pressure and rapid gas decompression in the oil and gas industry. The test standards and methods The NORSOK M-710 standard specifies the specific conditions and steps of the test: Test...
In Liquefied Natural Gas (LNG) operations, valves and equipment face some of the harshest conditions on Earth: temperatures plunging below -320°F (-196°C), pressures exceeding 750 psi, and constant thermal cycling that causes hardware expansion, shrinkage, and material stress. These challenges demand seals that can maintain integrity over the long term while ensuring safe, leak-free operation. Eff...
When it comes to sealing solutions in extreme environments, FFKM O-rings stand out as a top choice for industries demanding uncompromising performance. FFKM, or Perfluoroelastomer, is a high-performance material known for its exceptional chemical resistance, thermal stability, and durability. What Are FFKM O-Rings? FFKM O-rings are sealing components made from Perfluoroelastomer, a synthetic rubbe...
Valve stem packing seals are used in valves to provide a seal around the valve stem (the shaft that controls the valve's opening and closing). They are essential for preventing fluid or gas leakage from the valve, ensuring that pressure and contaminants don't escape. The application of stem packing seals includes: Pressure Control: They help maintain pressure within the valve, preventing leakage a...
Reducing fugitive emissions has become a high-priority goal for nearly all processing plants and facilities around the world. Often, the valve technology itself has a significant impact on fugitive emissions and therefore the life cycle cost of the equipment. According to the research, one of the largest sources of fugitive emissions in plants is associ ated with valves. The bulk of valve emission...

In the oil and gas industry, ensuring leak-free connections in high-pressure and harsh environments is critical. Weco Hammer Union Seals are designed to provide reliable one-way, high-pressure, and static sealing for a wide range of applications. These seals are widely used in static and low-speed sealing scenarios, offering excellent performance even in challenging conditions such as light gas, r...
In oil and gas well completion, production, or workover operations, controlling fluid communication between the annular area (the space between the casing and production tubing) and the interior of the production tubing is critical. To achieve this, the Seal Stack serves as an efficient sealing solution, widely used in wellbore tools, especially in key equipment like sliding sleeves. This article ...
(I) Application in hydraulic cylinder 1. Piston seal: The piston seal located on the piston head is usually made of rubber or plastic. Its main function is to prevent hydraulic oil from leaking from the piston head. During the operation of the hydraulic cylinder, the piston seal can maintain good sealing performance under different working pressures by virtue of its own material characteristics, e...
